Clinical perspective, offered as context rather than as advice.

Epigenetic implications of GLP-1 therapy and maintenance dosing: emerging evidence suggests that sustained weight loss and metabolic improvement may produce epigenetic changes (DNA methylation, histone modification) that persist beyond drug discontinuation[1].

This is speculative but fascinating: could long-term GLP-1 agonist treatment "reprogram" metabolic gene expression? If so, it would explain why some patients maintain weight loss better than others after discontinuation.

More research needed, but the concept of pharmacologically-induced epigenetic remodeling is intellectually exciting.

STEP 5 long-term data on maintenance dosing: the 104-week (2-year) extension showed sustained weight loss of -15.2% with continued semaglutide vs weight regain in the discontinuation group[1].

Key insight: weight loss continued to accrue between weeks 68 and 104 in many patients, suggesting the nadir may not occur until year 2+. The 68-week primary endpoint in most trials may underestimate maximal efficacy.

This supports long-term, open-ended treatment rather than fixed-duration "courses" of therapy.

A narrower follow-up, since the general answer is now clear:

What actually belongs on a baseline panel, as opposed to the enormous list that gets pasted around here?

Pregnancy after maintenance dosing weight loss: stopped GLP-1 medication 5 months before TTC as recommended. Was terrified of regaining weight during pregnancy.

Worked closely with my OB and MFM. Gained 25 lbs during pregnancy (within recommended range). Baby is healthy. The metabolic improvements from pre-pregnancy weight loss gave both of us a healthier pregnancy.

If you're planning pregnancy, discuss the medication discontinuation timeline with your OB. GLP-1 agonists are NOT safe during pregnancy.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
